LUBRICATING COMPOUND.

Application filed May 11,

To all whom it may concern:

Be 1t known that I, RALPH Paola J UDD, a

citizen of the Cleveland, in the United States,

residing at county of Cuyahoga and e invented certain new and useful Improvements in Lubricating Compounds, of which fication.

the following is a speci- My invention relates to improvements in lubricating compounds, and more particularly to that class or type of such compounds which are designed and adapted for use in lubricating the bearings of heavy machinery, the improved lubricant being particularly well jected to great W adapted for use in bearings sub eight and use, as for example heavy bearings or gears in machinery, car axles, and the like.

The improved lubricating compound possesses the desired properties of not gumming, of retainin g a uniform consistency,

of being nonfrictional, of being cooling and non-congealable in traordinary degre its properties to an exe, and consequently is not rendered particularly thin in the summer season or during tures, or in the winter low temperatures.

relatively high temperaseason or during very My improved lubricatlng compound preferably comprises the folowmg ingredients prepared and combined in the manner hereinafter referred to, and

Lubricating oil Zinc white in substantially the following proportions:

1 part. 10 parts.

The zinc white (oxide of zinc) and the lubricating oil ma merclal form.

In preparing the above, dred pounds of zinc white is 11y incorporated in about lubricating oil, or

a finely ground or divided .condition, and i: then added to the lubricating oil, the latte] being constantly stirred so that the entir mass will be thoroughly commingled.

After the Whole mass has been thoroughly mixed, it is still further reduced to the required consistency by any suitable grinding process, after which the compound will be ready for use or in condition for transporta tion in proper receptacles.

Under certain conditions other ingredients may be added to the above by correspondingly reducing the proportion of the zinc white. For example, under certain conditions finely divided graphite and asbestos may be added, say by reducing the zinc white to six parts and adding two parts graphite and two parts asbestos, orif desired,adding four parts of graphite to six parts of zinc White.

Having thus described my improved lubricating compound, and a suitablemeans for making the. same, what I claim and desire to secure by Letters Patent, is,-

1. A lubricating compound, consisting of lubricating oil impregnated with and thickened by finely divided zinc white in substantially the proportion of one part of the former and ten parts of the latter.

2. A lubricating compound, consisting of oil thickened by finely divided zinc white and graphite in substantially equal proportions of the two latter.

3. A lubricant compound, consisting of a lubricating oil thickened and reduced to a heavy consistency by the incorporation and grinding therein of six parts zinc white, two parts graphite, and two parts asbestos.

4. A lubricant compound, consisting of lubricating oil thickened and reduced to a heavy consistency by the incorporation and grinding therein of finely divided zinc white, graphite, and asbestos.

In testimony whereof I have afiixed my
